Lana71 [14]

-- Reflecting across the x-axis makes all the x-coordinates the negative of

-- Translating 2 units up makes all the y-coordinates 2 greater than
they were before the translation.  The x-coordinates don't change.

You didn't give us a list of new coordinates, so there's nothing
to match with.
